generic class ResolConstraint from AppParCurves
|
|
(MultiLine as any;
|
|
ToolLine as any) -- as ToolLine(MultiLine)
|
|
|
|
|
|
---Purpose: This classe describes the algorithm to find the approximate
|
|
-- solution of a MultiLine with constraints. The resolution
|
|
-- algorithm is the Uzawa method. See the math package
|
|
-- for more information.
|
|
-- All the tangencies of MultiPointConstraint's points
|
|
-- will be colinear.
|
|
-- Be careful of the curvature: it is possible to have some
|
|
-- curvAature points only for one curve. In this case, the Uzawa
|
|
-- method is used with a non-linear resolution, much more longer.
|

|
Bern, DerivativeBern: Matrix; Tolerance: Real = 1.0e-10)
|
|
---Purpose: Given a MultiLine SSP with constraints points, this
|
|
-- algorithm finds the best curve solution to approximate it.
|
|
-- The poles from SCurv issued for example from the least
|
|
-- squares are used as a guess solution for the uzawa
|
|
-- algorithm. The tolerance used in the Uzawa algorithms
|
|
-- is Tolerance.
|
|
-- A is the Bernstein matrix associated to the MultiLine
|
|
-- and DA is the derivative bernstein matrix.(They can come
|
|
-- from an approximation with ParLeastSquare.)
|
|
-- The MultiCurve is modified. New MultiPoles are given.
